  • the invention relates to a liquid filter according to the preamble of patent claim 1.
  • Fluid filters known in the state of the art are very frequently equipped with return-blocking diaphragms and return-blocking valves, in order to prevent fluid leakage from the filter when the internal combustion engine is stationary and, in addition, to prevent leakage of the fluid from the filter when the filter is replaced.
  • an exchange filter for liquids which comprises a non-return membrane.
  • the DE 41 40 140 A1 shows a Anschraubfilter for liquids, especially lubricating oil filter for internal combustion engines.
